DISINTE GR ATING-TOOL FOR SUGAR IN BARRELS.

SPECIFICATION forming part of Letters Patent No. 545,878, datedSeptember 10, 1895.

Application filed March 21, 1895. $erial No. 542,578. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN DENNISON, a citizen of the United States,residing at Fort Wayne, in the county of Allen, in the State of Indiana,have invented certain new and useful Improvements in Disiutegratinglools for Sugar in Barrels; and I do hereby declare that the followingis a full, clear, and exact de scription of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which formpart of this specification.

My invention relates to improvements in disintegrating-tools for sugarin barrels. It is well known that sugar. put up in barrels soon becomes,when opened and in the hands of retailers, a solid, compact mass, oftenimpenetrable not only to the retailing scoop but also to an ordinarytool, and in this condition is extremelydifficult andinconvenient tohandle.

The object, therefore, of my invention is to provide a cheap,substantial, and easily-operated tool adapted to disintegrate and loosenup a compact mass of sugar in barrels by relieving the mass of itslateral support at diametrically-opposite points by an outward pressureagainst the sides of the barrel simultaneous with the disintegratingaction of a pair of rotary cutting blades or wings upon the lower end ofthe operating-shaft.

Myinvention comprises an externally screwthreaded shaft carrying uponits lower end an operating-handle and having adjustably mounted thereona pair of radial oblique arms adapted to secure an outward pressure upondiametrically-opposite points on the perimeter of the containing-vessel.

Similar figures of reference indicate corresponding parts in the severalviews.

Figure 1 is a side elevation of my improvement, showing the relativeposition of the operative parts with a portion of one of the obliquearms broken away to show its pivotal connections. Fig. 2 is a plan ofone of the oblique arms, showing the parallel members and their rigidconnection. Fig. 3 is a plan of the two-bladed rotary cutting-knife.Fig. 4 is a plan of the screw-threaded collar in which the inner ends ofthe toggle-levers are pivotally mounted. Fig. 5 is a plan of theslidable collar in which theinner ends of the obliquelever-arms arepivoted. Fig. 6 is a side view of my improvementin position in asugarbarrel, showing the simultaneous action of the oblique lever-armsand the rotary cuttingblades upon the compact contents thereof.

All parts of my improvement excepting the handle are preferably ofmetal.

The vertical operating-shaft l is externally screw-threaded throughoutits length, excepting at its extremities, has upon its lower end acone'shaped point 15 and upon its upper end a hollow cylindrical head 16in which the operating-handle 21 is removably mounted, and is providedwith a neck 17 integral therewith.

The oblique arms 2 are formed of two substantially-parallel bars, asseen in Fig. 2, having their outer ends slightly spread and rigidlyconnected by the pin 13, thereby giving them greater strength and abearing against the barrel sides at two points for each arm. The outerend of the said bars are preferably claw-shaped to give a firm grip whenin position for spreading the sides of the barrel. The arms 2, thusconstructed, are pivotally mounted at their inner end upondiametrically-opposite sides of the slidable collar 7 by means of theperforated lugs 8 and the pins 11. The said collar7 is loosely mountedupon the said shaft 1, and is limited in its upward movement by thescrew-threaded thumbnut 6 on said shaft. The said shaft 1 is provided ator near its lower end with a collar 9 mounted thereon by ascrew-threaded connection, and provided upon its opposite sides withapair of lugs 20, in which the lower ends of the oblique toggle-levers 3are pivotally mounted by the'pivots 10, the outer and upper end of thesaid levers 3 being pivotally connected to the oblique arms 2 by thepins 12 at a point preferably about midway their length. The said shaftis also provided at its lower extremity with a knife rigidly mountedthereon, and provided with the oppositely-arranged horizontalcutting-blades 4 and 5, the cutting-edge of each being upon the sideopposite to that of the other, as seen in Figs. 1 and 3. The saidknifeis removably mounted in position on said shaft and is rigidlysecured thereon by the jamnut 14. The blade 4 is preferably twice thelength of the blade 5, and the cutting-edges of the said blades arearranged upon different planes, so that the shorter blade 5 outs inadvance of the blades 4.

The manner of operating my improvement thus briefly described is asfollows: The tool is placed in position in the top of the barrel 18, asseen in Fig. 6, with the point 15 inserted into the center of thecontents 19. The arms 2 are then spread until their outer claw-shapedends impinge upon or grip the sides of the barrel. This is done bylowering the slidable collar 7 supporting the upper ends of the saidarms by means of the screw-threaded nut 6, and when desired the sides ofthe said barrel can be still farther spread by a further lowering of thesaid nut on the said shaft. The spreading of the sides of the saidbarrel in one direction will thus relieve the compact mass of itscorresponding lateral support and will also simultaneously compress thesaid mass with equal force upon its opposite sides, thus tending tobreak it up, and the mass will thus offer less resistance to the actionof the cutting-blades. The operator.

now rotates the said screw-shaft 1 by means of the operating-handle 21,being rigidly supported in its upright position by the said obliquelever-arms 2. The rotation of the said shaft carries with it the fixedcuttingblades 4 and 5, adapted to cut concentric openings, preferably ofa diameter of eight and sixteen inches respectively. The spreadingaction of the said arms upon the containing-barrel thus materiallycontributes to the ease and facility with which the hard and compactmass 19 is broken up and disintegrated. It is obvious that the rotationof the screw-shaft 1 in operating the said cuttingblades will in no wiseaffect the relative position of the said collars 7 and 9 thereon, noraffect in the least the outward pressure of the said arms 2, though, ofcourse, the revolution of the said shaft will constantly vary therelative position of the supporting-collar 9 and the said cutting-blades4 and 5.

When it is desired after the above operation to remove my improvementfrom its'fixed position in the said barrel, it can be readily done bysimply rearwardly rotating the said thumb-nut 6 on the shaft 1, and thenslightly elevating the said slidable collar 7, when the arms 2 willrelax their hold and the tool can be lifted out. By arranging the saidthumbnut 6 upon the neck 17 of the shaft 1 the said arms 2 and thetoggle-levers 3 can be folded into a position practically parallel withthe said shaft, and by removing the handle 21 and the saidcutting-knife, my improvement can be packed into a convenient andcompact form for shipment or storage. It is obvious that the mere formand proportions of the said cutting-blades and of the said oblique arms2 are immaterial and may be variously modified in various details ofconstruction without departing from the spirit of my invention. It isalso obvious that my improvement is equally well adapted fordisintegrating salt in barrels and numerous other articles ofmerchandise.

Having thus described my invention, what I desire to secure by LettersPatent is 1. A disintegrating tool for the purpose specified, comprisinga screw threaded rotary shaft having upon its lower end the rigidcutting blades 4 and 5, apair of pivotally mounted oblique arms, mountedas shown, for the.

purpose described, and provided with the toggle levers 3 pivotallymounted in the screwthreaded collar 9, all substantially as described.

2. In a disintegrating tool for sugar in barrels, the combination of thescrew threaded shaft 1 having an operating handle in the top thereof,the cutting blades 4 and 5 removably fixed upon the lower end of saidshaft, the oblique arms 2 ptvotally mounted in the slidable collar 7 onsaid shaft, the toggle levers 3 pivotally mounted in the screw-threadedcollar 9 and having their upper end pivotally connected to the saidarms, and the screwthreaded thumb-nut 6 adapted to vertically adjust thesaid collar 7 on said shaft all substantially as described.

3. In a disintegrating tool for the purpose specified, the oblique arms2 pivotally mounted at their upper end in the slidable collar 7, andpivotally supported at their central portion by the levers 3, and havingat their free end a claw shaped termination to secure a holding gripupon the sides of the barrel in which it is placed, the toggle levers 3pivotally mounted in the screw threaded and vertically adjustable collar9, and having their outer ends pivotally connected to the arms 2 asshown, and the screw threaded thumb-nut 6 adapted to adjust and securethe said collar 7 in position on said shaft 1, all substantially asdescribed.

Signed by me at Fort Wayne, Allen county, State of Indiana, this 11thday of March, A. D. 1895.
